I agree, they run typically at ~140F which is at the borderline of what I think it is a good working temperature, no question about that. I also stated that any heat spikes were not going to help the situation. But, there is in an inverse relationship regarding stress and heat. The higher the load (stress), the lower the working temp. This goes for almost any construction material.
There have been other threads in other forums regarding this and the primary thesis is that the Vortechs are essentially tank killers. Since much of these discussions originate here in this thread, I think this is the place to try to correct that. Whether they become problematic in other tanks remains to be seen.
